We quantify the mechanisms for manganese (Mn) diffusion through graphene in Mn/graphene/Ge (001) and Mn/graphene/GaAs (001) heterostructures for samples prepared by graphene layer transfer versus graphene growth directly on the semiconductor substrate. These heterostructures are important for applications in spintronics; however, challenges in synthesizing graphene directly on technologically important substrates such as GaAs necessitate layer transfer and annealing steps, which introduce…

Improving Graphene Diffusion Barriers via Stacking Multiple Layers and Grain Size Engineering
It is shown that the performance of graphene diffusion barriers can be enhanced by stacking multiple layers of graphene and increasing grain size. The focus is on large-area barriers of graphene
Direct growth of graphene on GaN via plasma-enhanced chemical vapor deposition under N2 atmosphere
One of the bottlenecks in the implementation of graphene as a transparent electrode in modern opto-electronic devices is the need for complicated and damaging transfer processes of high quality
Graphene as an atomically thin barrier to Cu diffusion into Si.
The time-dependent dielectric breakdown (TDDB) test is used to evaluate graphene as a Cu diffusion barrier under real device operating conditions, revealing that both large- grain SLG and MLG have excellent barrier performance, while small-grain SLG fails quickly.
Direct Growth of Graphene Film on Germanium Substrate
By ambient-pressure chemical vapor deposition, large-scale and uniform depositon of high-quality graphene directly on a Ge substrate which is wafer scale is demonstrated, allowing integration with high-volume production of complementary metal-oxide-semiconductors (CMOS).
Electronic and Mechanical Properties of Graphene-Germanium Interfaces Grown by Chemical Vapor Deposition.
From this work, it is clear that the interaction between graphene and the underlying Ge is not only dependent on the substrate crystallographic orientation, but is also tunable and strongly related to the atomic reconfiguration of the graphene-Ge interface.
Graphene as a tunnel barrier: graphene-based magnetic tunnel junctions.
It is demonstrated that graphene can function as an effective tunnel barrier for both charge and spin-based devices and enable realization of more complex graphene- based devices for highly functional nanoscale circuits, such as tunnel transistors, nonvolatile magnetic memory, and reprogrammable spin logic.
Growth mode and structures of magnetic Mn clusters on graphene
We present a systematic study of Mn clusters on graphene by first-principles calculations. We show that the growth of Mn on graphene follows a three-dimensional (3D) mode. Both adsorption and

It is found out that acetic acid is the most effective PMMA stripper among the typically used solutions to remove the PMMA residue and that an optimized annealing process can reduce the height of the wrinkles on the transferred graphene layer without degrading the graphene quality.
Direct Synthesis of Large-Area Graphene on Insulating Substrates at Low Temperature using Microwave Plasma CVD
Key to this report is the use of 0.3 sccm CO2 during growth to put a control over vertical graphene growth, generally forming carbon walls, and 15–20 min of O3 treatment on as-synthesized graphene to improve sheet carrier mobility and transmittance.
Effects of defect density on ultrathin graphene-based metal diffusion barriers
The authors investigated the effects of defect density on the performance of monolayer graphene as a barrier to metal diffusion. The defects were introduced to the graphene by controlled
